...The American school counters this, claiming that the American synthesis is correct and calling it Rutherfordium. Element 105 was obtained in 1967 by Khrerov et al., also from the Soviet Union, by bombarding 243 Am with 22 Ne, and was later produced in the United States by a different method, for which the Americans claim the name Hahnium. Element 106 was produced in 1974 by A. Ghiorso et al. at the Berkeley Laboratory in the United States, by bombarding 249 Cf with 18 O, and by Khrerov et al. at the Dubna Nuclear Institute in the Soviet Union, by bombarding a silver target with 54 Cr ions. *Some of the terminology explanations that mention "Hahnium" are listed below.

…これに対してはアメリカ学派の反論があり,アメリカにおける合成が正しいとしラザフォージウムRutherfordiumという名称を主張している。105番元素は1967年同じくソ連のフレーロフらによって243Amを22Neで衝撃して得られ,その後アメリカでも別の方法でつくられ,これに対してアメリカからハーニウムHahniumという名称が主張されている。106番元素は1974年アメリカのバークリーBerkley研究所でギオーソA.Ghiorsoらが249Cfを18Oで衝撃して,またソ連のドゥブナ原子核研究所でフレーロフらが銀のターゲットを54Crのイオンで衝撃してつくっている。… ※「Hahnium」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
